The present invenion relatos to iniproioment# in Starting erioos for zinionniliilri. Onepof tl'ioimportzint objects of the presentinvention is to provide n starting dovice for inerneil combustion engines which includes a Simplified drive mof'lnininm for one of the rotn'iing paris oi' the engine Snell :is for rr;- :nnplo the H V wheel.

ln the drawing wherein for the purpose of illustration is shown the preferred em embodiment of my invention, the numeral 1 designates the drive shaft which extends from any snioiilo prime mover suoli as for vxiiinplo :i starring motor, not. shown.

The oper-ation of my improved starting device 'ne liriofilwlf stated as follows With rior. parts arranged as shown 'the drawing, iie driving gear or pinion l() which is secured on the outer end of tho driven snuff. 3 is our, of engagement with the gear teeth i3 formed in the peripheral edge of the 'iy wheel i4. The expansilile coil spring i6 norn'milj;Y holds the axial movable driven Shaft in outermost position and the pinion 2 wiiiolifis secured on tho miler end of drivo Bliaft 1 is in engzigemrnl: with die spiral gen1' 1.7 at all times.

lateral thrust is exerted on the driven shaft whereby the same will move inwardly. As the driven shaft 3 moves axially in an inward direction, the coil spring 16 will be compressed and the gear or pinion 10 will be broughtinto engagement with the 'ear teeth l?, of the ily wheel 14 thus provi ing a cooperationbetween the starting motor (not shown) and the fly wheel for starting the internal combustion engine. As soon as the motor starts` the parts rotate and move in the reverse direetion causing the pinion 10 to be disengaged from the gear teeth i3 and also, the coil spring'l will return the axially movable driven shaft 3 to its initial position .shown in the drawing.

Itwill thus be seen from the foregoing description that a starting device for internal combustion engines has been provided| which is very simple in eonstruetion and Operation an which will furthermore at, all times be positive and ellieient in carrying out the purposes for which it is designed.

The drive gear may be positioned at right angles to the driven shalt if so desired.

V'nile I have shown the preferred embodiment of my invention it is to be understood that minor changes may be made in the invention without departing from the spirit ol' the invention and the scope of the appended claim.

Having thus described what l claim is:-

In an engine starting device of the class the invent ioni;

described, a support including spaced side walls provided with registeringr openings, bushings arranged in the respective openings, a driven shaft journaled at its end portions in sa'Kl bushings, said driven shaft being:v adapted for axial movement, the inner end of the driven shaft being reduced, a cover plate secured on the outer face of the inner side wall of Said Supl` port over the opening therein, said Cover plate being provided with a'n opening Jlirough which the reduced inner end of the driven shaft exiends, a gear mounted on the outer end of the driven shaft and adapted to engage a member of the engine to be started, a drive shaft arranged in parallel spaced relation with respect to the driven shatta driving pinion secured on the outer end of said drive shaft, a relatively Wide spira-l gear keyed on the driven shaft at the intermediate portion thereo'l', said spiral gear cooperating with the driving pinion on the drive shaft. to effect the axial movement of the driven shaft whereby the gear mount- A ed on the outer end of the driven shaft is moved into operative engagement with said aforementioned member, and a normally exansible coil spring encircling the driven shaft and disposed between the inner end of the wide spiral gear keyed on the'driven shaft, and the inner bushing for returning the driven shaft to its initial position in testimony whereotl I aflix mv signature.
